Again you are exposing your ignorance of economics here. The dollar is a debt note. A fiat paper stand in for real capital. Real capital is things such as gold, real estate, cars, etc. Commodities. The dollar is an IOU note.
The dollar is real capital. It's the most popular real capital in the world. This is a fact.
The question is not will Bitcoin be above $500000 by 2020, it is what will $1 be worth?
You still failed to answer this question, because you can't do it. You can't name any other currency or basket of currencies to compare against in any meaningful fashion. Don't talk to me about ignorance when you don't even know the answer to your own question, rhetorical or not.
Here's the definition of "real capital" since you are apparently unfamiliar with it:
Real capital
Wealth that can be represented in financial terms, such as savings account balances, financial securities, and real estate.
You're just making stuff up off the top of your head and proclaiming it as law while being snarky about it at the same time. Not a good look.
